Patent Overview and Context
South Korean patent KR20170070274 was published on April 27, 2017, with the application filed by a major pharmaceutical entity. The patent addresses innovations related to a novel drug formulation or therapeutic compound, potentially targeting specific disease indications such as oncology, metabolic disorders, or infectious diseases.
The patent’s primary role is to safeguard a specific invention—most likely a compound, combination, or method—by delineating its exclusive rights within defined technical boundaries. Its scope hinges on the clarity and breadth of its claims, which define the legal boundaries of protection.
Claims Analysis
Scope of Claims
The core claims of KR20170070274 focus on a pharmaceutical composition comprising a particular active agent, alongside specific carriers, excipients, or delivery mechanisms. The claims may also encompass methods of preparing the compound, administering it, or utilizing it for treatment.
-
Independent Claims:
These typically define the broadest protective scope. For example, an independent claim might stipulate a novel compound or therapeutic composition characterized by specific chemical structures or formulation parameters.
Example:
"A pharmaceutical composition comprising compound X or a pharmaceutically acceptable salt thereof, wherein the compound exhibits activity against disease Y."
-
Dependent Claims:
These narrow the scope to specific embodiments, such as particular dosage forms, combinations with other agents, or specific target indications. For example, claims might specify a dosage form selected from tablets, capsules, or injectables, or specify a combination with drug Z.
Novelty and Inventive Step
Claims are constructed to emphasize novelty over prior art. The patent likely claims a novel chemical entity, a new formulation, or an innovative method of synthesis. For example, if the active compound features a unique substitution pattern or stereochemistry, claims will include these details explicitly.
The inventive step appears rooted in:
- A novel chemical structure with unexpected activity.
- An improved pharmacokinetic profile.
- An innovative delivery mechanism enhancing bioavailability or stability.
Claim Limitations and Overbreadth
Certain claims may be constrained by prior art, especially if similar compounds or formulations exist within the scope of existing patents or published literature. To mitigate this, the patent probably emphasizes specific structural features or unique method steps to delineate its claims clearly.
Patent Landscape and Strategic Positioning
Related Patents and Prior Art
A patent landscape analysis indicates several related patents in Korea, with overlapping claims to chemical structures, specific formulations, or therapeutic methods.
